Benefits of technology

The invention provides a method for analyzing video data and displaying relevant content to a user. The method uses supplementary data, such as tags or lower activity levels, to efficiently present relevant video material. Only a part of the video data is displayed, so as to reduce the time for viewing. The method also allows for automatic tagging and analysis of video data based on activity levels or sound detection. The analysis results in a text file with hyperlinks to relevant parts of the video data. A video investigation can be performed without requiring human interaction with the computer program. The technical effects of this patent involve improved efficiency and effectiveness in analyzing and displaying video data.

Problems solved by technology

Analysts and investigators involved with using these video data as an investigative resources face an enormous workload.

embodiments

[0032]A general outline of the method according to the invention is presented in the following. Forensic video material (forensic video data) data may be recorded by surveillance cameras. Further, today most of the people have the ability to record audio and video material anytime and anywhere, using their mobile phone. In case of a serious event or attack there is usually a lot of such material available. This material needs to be analyzed by the police during the investigation. Analysis requires many people and many working days to scan the huge amount of material submitted by the population. With the help of available software tools the analysis time can be reduced quite dramatically compared to a pure manual review of all the submitted material.

[0033]However, even with this software there is nevertheless too much data submitted by the population, so that an investigation cannot be completed in a timely manner. Material which is more likely to be helpful for the investigation sho...

Abstract

The invention provides a method for processing and analyzing forensic video data using a computer program, the method comprising the steps of recording the forensic video data; providing supplementary data related to the recorded video data, wherein the supplementary data may be provided from or input by a source external of the computer program, in particular a human, or wherein the supplementary data may be extracted from the forensic video data by the computer program in an initial analyzing step; analyzing the forensic video data by the computer program using the supplementary data; and displaying a part of the forensic video data, the displayed part being based on a result of the analyzing step.

Description

FIELD OF THE INVENTION[0001]The invention refers to a method for processing and analyzing forensic video data using a computer program.PRIOR ART[0002]Video analysis has become a significant forensic resource for investigation processes related to crimes and during court proceedings. Since the introduction of video as a forensic resource, the volume of available video data has increased dramatically, in particular with sources such as mobile phones and social media, in addition to surveillance cameras at streets, places and stadiums, for example. Analysts and investigators involved with using these video data as an investigative resources face an enormous workload. An existing software platform offers an easy and efficient user interface built on a set of video analytics. The purpose of this platform is to process and analyze large quantities of video data. The embedded algorithms process video sequences by detecting, recording, and classifying the depicted elements of interest. As t...
